10 Best Mini Split Ac Unit For Semi Truck 2025 in the United States

The Treeligo 12V Truck Air Conditioner is designed specifically for vehicles like semi-trucks, RVs, and construction equipment, offering a solid 12,000 BTU cooling capacity. This allows it to quickly lower the temperature inside your truck cab, which is especially beneficial for long hours on the road in hot weather. It uses inverter technology, enabling the compressor to adjust its speed based on cooling needs, which helps save battery power and ensures quiet operation at around 45 decibels—similar to a quiet conversation. The AC is powered by a 12-volt system compatible with your truck’s battery and can run with the engine off to reduce fuel consumption.

Installation is straightforward thanks to included accessories and instructions, and the durable ABS plastic housing resists corrosion and weather damage, making the unit suitable for harsh environments. While the energy efficiency is limited with a 1-star rating and a SEER of 1, indicating higher power consumption compared to other units, this may be a factor if you rely heavily on battery power without frequent engine running. The noise level, although relatively low, might still be noticeable in very quiet cabins.

The unit offers remote control and multiple operating modes (energy saving, sleep, powerful), adding convenience and flexibility. It also features a dehumidification function that can help reduce moisture inside the cabin. Backed by a 1-year warranty and positive customer feedback, it serves as a reliable cooling solution for truck drivers seeking easy installation and dependable performance, though it may not be the best option if minimizing battery drain over long periods is a priority.

The Mieligo 12V Truck Air Conditioner offers 10,000 BTU cooling power, which is solid for providing comfortable temperatures inside semi-truck cabs and similar vehicles. It uses a DC inverter compressor, which is good for quickly adjusting cooling output and maintaining energy efficiency, helping to save power during use. The system is a split type with separate indoor and outdoor units, making it easier to install in trucks, trailers, and even equipment like cranes or RVs. It runs quietly at about 45 decibels, so it won’t add much noise to your cab environment. The brushless fan improves durability and keeps the noise low, which is helpful during long trips or parking.

A copper evaporator inside ensures efficient cooling, although this part can add to the cost. The unit comes pre-charged with refrigerant, which simplifies installation and avoids extra hassle or expense. You also get remote and panel controls for easy operation, plus an air filter to keep the air inside clean. The system weighs around 70 pounds, which is manageable for installation by professionals. For those concerned about moisture, the unit also helps with dehumidification, keeping the cab comfortable and less sticky.

This AC model is well suited for truck drivers who need reliable, quiet, and efficient cooling during both driving and parking conditions, especially if you want easy installation without extra refrigerant costs.

This 12V mini-split air conditioner is a solid choice for semi truck drivers and others needing efficient cooling in vehicles or small mobile spaces. With a strong 12,000 BTU cooling capacity, it cools quickly and can handle larger areas like truck cabs or RV interiors effectively. Its 12V DC power means it’s designed specifically for vehicles, allowing easier installation without complicated electrical work. The split system design saves space inside the vehicle by separating indoor and outdoor units, which is helpful for cramped truck cabins. Noise is reasonably low at 55 decibels, roughly the sound level of a normal conversation, so it shouldn't be too distracting during rest. It also comes with a remote control for convenience. The aluminum evaporator helps keep the price competitive, offering good value though it may not be as durable as copper alternatives.

Users need to self-refill the refrigerant, which might require some maintenance knowledge or professional help. Energy-wise, it uses about 15 kWh annually, making it fairly efficient for its size. While it lacks detailed smart features or advanced dehumidification functions, it covers the basics well. For those seeking reliable, easy-to-install cooling for their truck or mobile vehicle without extra frills, this unit presents a practical and effective solution.
